Thanks, John. My comments today will highlight our progress towards improving growth rates and the earnings profile of the company. Our actions in the fourth quarter were focused on improving the net interest margin while continuing to adapt our expense structure to support additional investment in new business generation, namely commercial lending and trust.
The successful completion of the FHLB advance restructuring and 2 branch consolidations provide an opportunity to defray the investment and the talent we need to drive organic growth. While the FHLB restructuring is largely a treasury activity, the consolidation of branch offices required careful communication with long-term customers to ensure a smooth and seamless migration to new facilities. Our success in this effort is measured by the expense reduction but also measured by our ability to retain customers that we'd expect to serve for many years. Our retail group has carefully worked with impacted customers since the formal notification in September, and we're pleased to report virtually 100% of deposits are transitioned to the new facilities, including 85% of safe deposit box customers, allowing for cost savings without significant impact to our retail deposit base.
In a related effort, the bank launched mobile Remote Deposit Capture, that is check capture via smartphone in the fourth quarter. This latest piece of our mobile banking infrastructure provided additional convenience for customers and the flexibility to make a material adjustment to branch service hours to further manage operating expense levels. While these initiatives will help to offset business development expenses, the branch hour changes were effective in mid-November and the branch closures were effective on December 28, so the actual impact of these initiatives will only be fully realized in the first quarter of 2014.
When considering the redeployment of operating expenses, it is important to note that adding seasoned and professional business development staff to the commercial lending and trust organizations is a long-term strategy. Investments of this nature take time to become accretive to net income. Notwithstanding that, early results in loan origination, loan portfolio growth and assets under administration are encouraging.
During the fourth quarter, 2 additional new hires were made to bring the commercial loan origination staff to a full strength of 11 calling officers and 13 credit support staff. While we continue to recruit credit support staff to support a growing commercial portfolio, the business development team required to produce commercial loan growth in 2014 is in place and assimilating well to our business model.
Additional hires will be considered as opportunities arise, but we now have the team we need to materially increase commercial loan market share in our core markets. Investment in business development staff in commercial lending is demonstrating tangible results as the bank posted its third consecutive quarter of net loan portfolio growth, driven by commercial loan growth of $26.4 million, or an 18.8% on an annual basis. In addition to commercial loan growth, the pipeline of committed commercial loans more than doubled versus prior year, growing from $23 million at December 31, 2012, to $59 million at December 31, 2013. The yield related to the commercial pipeline is a respectable 4.39%, allowing commercial loan growth to replace maturing bonds at an average yield of 1.66%.
In addition to commercial loan growth, the demand for residential construction-to-perm loan continues to grow. While still modest in relation to the bank's balance sheet, 84 construction-to-perm loans totaling $33.7 million were originated in 2013, with volumes increasing every quarter. An additional $10 million of these loans were in the pipeline at December 31, with an average yield of 4.07%. Interestingly, the majority of these loans are adjustable rate instruments, making them good additions to the bank's balance sheet.
Our secondary recruiting focus has been trust and asset management. Trust and asset management revenue grew $662,000, or 44% from $1.5 million to $2.2 million from 2012 to 2013. Further, assets under administration grew 25% from $172 million at December 31, 2012, $216 million at December 31, 2013. I should also note that in an effort to provide additional detail regarding this business, our earnings release now includes a disclosure of assets under administration.
While we are pleased with the growth levels into 2013, transforming this business into a more material revenue engine requires us to make additional investments into the business. In December, we announced the hiring of Craig Spengemen as Executive Vice President, Director of Trust and Asset Management. Craig joined the senior management team in January from Peapack-Gladstone Bank, where he spent 28 years building a $2.5 billion asset trust operation, that closely resembles the type of trust operation that would best complement our business.
The trust business at OceanFirst is squarely targeted at providing support to the senior citizen communities in our market and to our growing portfolio of business owners. These target clients have investable assets typically below the minimum target of most wealth management firms, have a strong desire for straightforward investment advice, are risk-adverse and have a strong appetite for fee-based estate planning and estate settlement services. So while trust and asset management enjoyed a very solid year, we're pleased to have the opportunity to make a substantial investment in a proven -- in the ability to our business to a new level. As Craig builds this business, we expect to make additional hires to our trust business development team.
With the recent additions to staff in commercial lending and trust, our business development team is approaching full capacity. Operating expense increases driven by hiring activities will now moderate as our focus shifts to assimilating the seasoned professionals that have joined our teams into the OceanFirst culture and to demonstrating incremental results in our key growth areas.
Balanced against our growth objectives is an absolute requirement that new business be pursued within a prudent and conservative risk management program. The bank initially established enterprise risk management in 2013 and substantially upgraded capabilities -- I'm sorry, established the program in 2003, substantially upgraded capabilities in 2013, with the addition of David Howard as Chief Risk Officer. Dave joined the bank after a successful career in risk management with Guggenheim Partners, Financial Guaranty Insurance Company and Fitch Incorporated.
Given the relatively modest loan loss provision for the fourth quarter and the need to evaluate the remaining allowance for loan and lease losses related to Superstorm Sandy, I'm going to ask Dave to spend a few minutes discussing changes to our ALLL position at year end.
